A suspension for a bicycle having a unified rear triangle pivotably connected to a Y shaped frame.

A shock absorbing means is connected to the Y shaped frame at the intersection of the arms of the frame and to the rear triangle. A pivot is preferably connected near the bottom bracket of the bicycle in order to reduce movement of the bottom bracket.
